I didn't say that Songye are Luba. I said that some people consider them as Baluba since that they are from Kasai. For example, like the way some people consider Mbala-people, Bayaka and Suku-people as Bakongo while they are not. There are different tribes in Kasai, such as Kanyok and Kete, but some people just bindly like them as Luba. Minister Constant Mutamba and singer Sam Tshintu are Songye, but people just call them Baluba.
